Enabling Open NAT Type for Two Xbox 360s

Enabling Open NAT Type for Two Xbox 360s

I have been having problems with gaming (joining/hosting games, etc). I've looked around this website on how to open the ports (3074, 88, 80, 53) with their respective TCP/UDP and have done that. So my question is how do I do this setup to allow two Xbox's on the network with open NAT types? I have a 3801HGV gateway.

Re: Enabling Open NAT Type for Two Xbox 360s

I tested the firewall setup with only one Xbox on the network, and all the ports opened for that Xbox, and I still end up with a restricted NAT type. So that solution did not work even for one Xbox, let alone two.

Hey guys. First time here. I did EVERYTHING described in the link in JefferMC's post here and I'm still getting a moderate Nat on one of my xboxes. I just dropped a hundred dollars on a router and am about to throw it through a wall. I need some troubleshooting guidance here.

Re: Enabling Open NAT Type for Two Xbox 360s

I have just upgraded my service from Uverse, Turbo Max to "Power". I had a 2wire modem with the Turbo Max service that two xbox's worked great with. I now have the Motorola NVG589 ("Moto") with the Power internet service. My xboxes DO NOT work well with a STRICT NAT TYPE.

I can get the first xbox (they are both hardwired w/ cat5 to the ethernet port on the Moto) to a "Open" Nat type by Firewall-Nat/Gaming...Port forwarding 3074, 88, 80, 53 with their respective TCP/UDP too. Those are dedicated to the first xbox's IP and not available for the 2nd xbox.

I attempted to connect a Lynksys/Cisco WRT610N ver2 router that has UpNp, Port Forwarding, DMZ, Port Range Forwarding, etc (pretty much this router worked fine and allowed open nat types on actually 3 xbox's simultaniously) to the Motorola NVG589. Anyway, long story short, I attempted this by AT&T phone tech support and I was at this for about 8 hours between getting transferred and trying many different things I was told to try. In the end I am still also at square one. The Moto passed data up to the end of the cat5 out of its ethernet cable but I could not get the Linksys router to work. It was transmitting its gateway, but when you connected to it, it would say "no internet connection".

I was going to run the two xboxes off the Linksys which would be "behind" as these techs called it, behind the Moto.

The description above, "Community – Accepted Solution" is talking through menus of a 2wire modem and how to possibly get this working. Also it is dated March of 2011. Yes they might be similar, but they are not precisely the same and these Menu's I have, or many people have. If you don't disable/enable something correctly in these menu's it turns into a coin flip.

So here are my questions:

1) Can a Motorola NVG589 alone support two xbox 360's and have an OPEN NAT type? if yes how? if no, go to 2).

2) If 1) is not possible, then can a Motorola NVG589 with a Lynksys/Cisco WRT610N ver2 router "behind" it support two xbox 360's and have an OPEN NAT type? if yes how? if no, go to 3).

3) If 1) & 2) are NOT possible, is there a proven certified hardware setup that can be configured w/ the Motorola NVG589 and 2 xbox 360's to provide an OPEN NAT type? if yes how? if no, go to 4).

@AirborneHoosier, unfortunately, most (if not all) of the regulars here have not themselves seen a NVG 589. I can tell you that it is actually configured more like an NVG 510 than a 2WIRE (Morotola uses the term IP Passthru where PACE/2WIRE uses the term DMZplus).

Re: Enabling Open NAT Type for Two Xbox 360s

So. I'm not at home but I've done this. Bought a router, dmz'd it, and enabled upnp but I'm still getting moderate NAT on one Xbox. Is it possible I need to start from scratch and reconfigure everything? I'm at a loss. Also, using a 2wire not Moto.

Re: Enabling Open NAT Type for Two Xbox 360s

Hi jmuzz07,

I think it may be best to start over by resetting the equipment and testing again. To test to see if it is working as it should, try just connecting one Xbox 360 to the U-verse gateway and put it in DMZ mode. Reboot the equipment after you do this, and then see if you are still having it report as a moderate NAT. If so, if a wireless connection, I would suggest removing the connection on your Xbox 360 and connecting back up.

If that works out, then you can put in the 3rd party router configured with uPNP enabled. You want to reset the router connections on the 2wire again, and set the DMZ mode to your router. This should work, but if not, the 3rd party router may need further configurations, as uPNP is definitely not working.
